This was NOT 144" wide.
Bought this to replace (thank you Allstate Protection Plan!) the Retractable Awning we purchased and installed in 2020.  I ordered the exact one, but when it came, it is a full 12" narrower than the original.  The PLAN was to use the same studs of the original install.  Nope.  We now have 6" on both sides that show the previous holes AND they don't shade ALL of our windows, which is why we needed the largest one! AND it doesn't close right!!  SOOOO disappointed and will be asking for a reparations.
